Procedure

To a mixture of 2-(2-methoxybenzyl)imino-5,5-dimethyl-1,3-thiazine(0.27 g), carbon disulfide (0.09 g) and N,N-dimethylformamide (2 ml) was added under ice-cooling 60% sodium hydride (0.05 g). The mixture was stirred for 30 minutes. Methyl iodide (0.17 g) was added thereto. The mixture was stirred at room temperature for 2 hours. To the solution was added water (30 ml). The mixture was extracted with diethylether (60 ml), dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (n-hexane/ethyl acetate) to give 2-(2-methoxybenzyl)imino-3-(methylthio)thiocarbonyl-5,5-dimethyl-1,3-thiazine (0.20 g, yield: 57%) as colorless oil.
